I was shown a quick way of removing tries from a wheel. This is to Select an inner edge and then to go to modeling drop down and then Dot Loop, this will select every over edge along that line of edges. Then you can remove these edges by clicking collapse.
This didn't actually work very well, shadows are being pinched up every edge making up the centre of the tyre.
I finally did the front window , i've been putting it off.
I actually did this about a week ago. I've since retopologized, done the interior, and unwrapped the majority of the car.
These images are showing the interior "Tub", All these parts in the image are also unwrapped, and have had the Average normals scripped ran on them.
